Military Installation Defence

The integration of small, commercially available unmanned aerial systems into military reconnaissance and attack operations has been one of the most significant tactical shifts of the past decade. From the battlefields of Ukraine to operations across the Middle East and Africa, small drones — many of them derived from consumer platforms costing less than USD 500 — have reshaped the threat environment for military installations worldwide. The ability of an adversary to conduct persistent, real-time surveillance of a military compound from beyond the effective range of small arms fire represents a fundamental challenge to base security that ground-based perimeter defences were not designed to address.

The Operational Threat to Military Installations

Military bases face a drone threat that spans several distinct mission types, each with different detection and response requirements.

Reconnaissance and battle damage assessment (BDA): An adversary operating a commercial quad-rotor at 200–400 m altitude can conduct persistent surveillance of a military installation’s layout, vehicle positions, troop concentrations, and equipment status. This real-time ISR capability was previously available only to state actors with satellite or manned aircraft access. Today it is available to any non-state actor with a USD 1,000 commercial drone and a smartphone.

Electronic intelligence (ELINT) collection: Drones equipped with passive RF scanners can map the electromagnetic signature of a military installation — cataloguing communication frequencies, radar emission patterns, and network access point locations — without any physical penetration of the perimeter.

Swarm harassment and saturation attacks: Low-cost commercial drones modified with small explosive or incendiary payloads are increasingly used in swarm configurations to overwhelm base defences. Even if only a fraction of a swarm reaches its target, the saturation of response capacity creates defensive gaps that can be exploited. Tracking and engaging multiple simultaneous small targets at low altitude is beyond the capability of standard military air defence radars optimised for larger, faster aircraft.

Proximity disruption: Even without a payload, a drone approaching a military helicopter landing zone during operations, a fuel point during resupply, or a command post during a briefing creates immediate operational disruption. The uncertainty about whether the drone is armed forces suspension of activities until the threat is resolved.

Cyrentis CR Series Capabilities for Military Deployment

The Cyrentis CR Series was developed with dual military and civil use requirements and incorporates specifications driven by military customer feedback through the development cycle. Key military-relevant capabilities include:

Micro-drone and nano-drone detection: The CR-PX10 and CR-PK13 close-range series detect targets with RCS as low as 0.01 m² — small enough to detect sub-100 g nano-quad platforms. Detection range for standard 250 g–2 kg military reconnaissance drones is 1.5–3 km depending on altitude and approach angle.

Low probability of intercept (LPI) operation: Cyrentis CR radars can operate in frequency-agile mode, varying their transmission parameters to reduce detectability by ELINT systems. In passive monitoring mode, Cyrentis CR units provide detection using only emissions from the target drone itself (Doppler processing against background), with zero active radar transmission.

Rapid deployment: The CR-PX10 portable variant sets up on a standard tripod in under 15 minutes by a two-person team and operates on battery or vehicle power (12 V DC). This enables deployment during expeditionary operations, forward operating base (FOB) establishment, and temporary site protection during exercises or high-threat periods.

Multi-sensor track fusion: Cyrentis CR radars can receive tracks from multiple radar units and fuse them into a single common operating picture (COP) display, enabling a combined-arms air picture over a large base complex without requiring a separate radar management system.

Effector integration: Cyrentis CR track data can be fed via standard TCP/IP and serial interfaces to RF jamming systems, hard-kill laser or kinetic systems, and net-gun platforms. The sub-second track handoff latency ensures that effector systems receive targeting data with sufficient time to engage before a fast-moving target closes to minimum safe engagement distance.

Model Selection and Quantified Coverage

Military installations need layered coverage: long-range warning outside the wire, precise wide-area surveillance over the base itself, and a signature-managed option for contested electromagnetic environments. The table below maps each layer to a Cyrentis CR model with its key figures:

Two worked examples for planning purposes:

• Fixed airbase perimeter: two CR-PX11 units on the main approach corridors provide 10 km warning depth — over ten minutes against a 15 m/s target — while a central CR-PX16 covers the airfield and aprons with 0.5 s TAS updates for cueing the base’s effector ring. A CR-FX20 covers the urban-facing or terrain-masked quadrant while keeping the overall emission signature low.
• Forward operating site: a CR-PX10 tripod pair emplaced on arrival gives immediate local coverage, replaced within days by a CR-FX20 on a telescopic mast once the position is established — its LPI waveform keeps the site’s radar signature minimal in a monitored electromagnetic environment.

All units fuse into a single common operating picture, so tracks initiated by the outer layer are handed to the inner layer and to effectors without operator re-acquisition.

Reference Deployment: Airbase Perimeter in a Contested Environment

An air force operating a forward airbase in the Middle East layered its counter-drone defence after reconnaissance quadcopters began appearing over the fuel farm and helicopter aprons. Two long-range turntable radars cover the open desert approaches, a digital-array radar at the airfield centre provides precision tracks over the base itself, and an FMCW unit watches the urban-facing quadrant where light civil traffic had previously generated nuisance alerts.

The base defence operations centre runs the fused picture on a single display: a detection in the outer layer raises the alert state, the digital-array radar assumes the priority track at 0.5-second updates, and cueing data flows to the jamming positions without a manual handover step. The force-protection review of the configuration noted the value of the low-emission FMCW layer in particular — the base can maintain continuous surveillance during heightened tensions without adding a locatable radar emission to its electronic order of battle.

Integration with Base Defence Architecture

Cyrentis CR radars integrate with military command-and-control architectures through standard interfaces including MIL-STD-1553B data bus compatibility (available on request), ASTERIX CAT-48 track output for air picture integration, NMEA position data for GPS registration with map displays, and REST API for integration with modern cloud-native command systems.

In fixed base applications, Cyrentis CR radars can be integrated with the broader base physical security system (BPSS), enabling drone detections to trigger automated lockdown procedures, gate closures, and standby alerts for quick reaction forces without requiring human decision-making in the detection-to-response loop.

For classified operational environments, Cyrentis CR radars are available in configurations that comply with TEMPEST and electromagnetic emissions requirements. For export to allied military customers, export licensing documentation is prepared in accordance with MOFCOM dual-use regulations.

The Cyrentis CR Series provides military commanders with an affordable, proven, and tactically flexible tool to close the airspace gap above their installations — transforming the overhead threat from an unmanaged vulnerability into a monitored and responsive defensive perimeter.

After radar establishes a track, an EO/IR sensor can provide visual or thermal confirmation and preserve image evidence for operators.
